13" F4.5 for Dennis Completed . . .

The very nice 13.1" f4.5 mirror includes a custom made mirror cover.

A complete Sky Commander system is installed. Note the dew shield.

GSO 2-speed focuser, curved-vane spider and easily-removed top ring.

The primary sits on a 6-point mirror cell.
 Larger knobs make collimation easy...
